Title: Amplifier circuit
Inventor: MATOBA TAKASHI
IPC: H03F3/45
Filed: 1995-04-11
Abstract: PURPOSE: To obtain an amplifier circuit capable of reducing input offset voltage and current consumption in a required circuit by self-matching a differential amplifier circuit and a push-pull output stage circuit connecting a resistor by two current mirror circuits and selecting FETs forming the circuit so as to satisfy the conditions of a specific equation. CONSTITUTION: An output from a differential amplifier circuit formed by FETs Q1, Q2, etc., is outputted through a push-pull output stage circuit formed by FETs Q13, Q14 connected through a resistor R8, etc., and output FETs Q11, Q12. Since the differential amplifier circuit and the push-pull output circuit are self-matched by two current mirror circuits formed by respective FETs Q5, Q6 and Q14, Q15, input offset voltage is reduced. The increment of current consumption in the circuit is prevented by the resistor R8, and when a voltage difference between two inputs is negative, current consumption in the circuit is also reduced. The FETs Q11 to Q14 are selected so as to satisfy the conditions of the shown equation.

IPC: G01S1/68
Filed: 1986-04-14
Abstract: PURPOSE:To allow a ground position to correspond to observed data, by setting a band not contributing to an observed band in a macrowave radiometer, and allowing a moving body provided with an oscillator of known position and speed emitting an electromagnetic wave of this frequency band to run inside an observation area. CONSTITUTION:A 15GHz band amplifier 6 is installed as the No.3 band for positioning excepting an observation band. An output signal of the amplifier 6 is classified into frequency f1 through fi on a few kHz basis by a filter 7 and an amplitude intensity is detected by a detector 8. Next, the amplitude intensity values obtained simultaneously from each filter by a parallel/serial convertor 10 via an A/D converter 9 are converted into one-dimensional values, and at this moment time data are added. The electromagnetic wave from an oscillator of the 15GHz band set on the moving body of known position and speed is collected by this micro-radiometer. And, by analyzing time data from the convertor 10 and amplitude intensity of each filter, time when an antenna scans the sky over a beacon station can be determined accurately and data of observation band corresponding to this time become the position data of the oscillator.
